This invention relates to a power transmittingvdevice, and is particularly adapted to connect a driving element witha. speed changing driven element, and is -ln the nature of an improvement uponv my gear shifting 'apparatus covered .by an appllcation for. Letters Patent of the United' States, filed July 21, 1914, Serial No. 852,320.

One of -the objects of my present inventionis to provide improved means whereby the hand operated levers of an lautomobile mayibe connected with its driving element, 'when` the foot pedal of the. automobile is operated to disconnect it from its driving element.

Another object is to provide the shifting mechanism of an automobile with means. adapted to positively indicate whether a gear was properly shifted, said indicating means being in the form of hand leversadapted Vto 'shift the gears in au ordinary manner in case of an emergency;

3A further object is to provide improved means whereby the clutch cont-rolling lever becomes adapted to connect positively the driving element of a machine with a s eed changing element when said contro ling lever is operated to disconnect the machine from the driving element.

A further object is to provide improved means whereby the interchangeable gears of a machine provided with a clutch for disconnecting it from its driving element arel shifted before the clutch is released to conneet the machine with its driving element.

A further object is to provideimproved means adapted to prevent the shifting. off

the gears of a machine when itV is connected wlth its driving element.

A further object is to provide improved'l means adapted to prevent the shifting of any one of a set of gears except after the entire set has been neutralized. y

A further object is to provide means whereby ra shaft, rotated by the drivingV the speed of the machine during one revoluthe driving element, and to cause gear.

tion followil ig the disconnection ci the driving element from the muchinel A further object' 'is to provide .means whereby a siaft operated by the driving element of an automobile is connected with itsgear shii ting mechanism whene foot pedal is operated to disconn to actuate sa: d mechanism first to gears into a. n eutral position and last to shift one of the gears into apreselected speed changing position.

A further object is to provide a power transmittin mechanism Vadapted to connect a driven cement of a machine lwith its driving element with an element adapted to yield tothe driven element when said element fails to respond to the driving element.

With the above and related objects in view,"this i1 vention comprises the means hereinafter described, a practical application whereof is illustrated in the accompanying drawing s,- and embraced within the scope of the appended claims.

prevent the sliii'table gear from herinnering the other gear. It will be observed that the position. of each of the shiltable gears is indicated by the levers 28 and 28, that is, when said gears are in a neutral position, said levers are .in a vertical position, and when a shiftable gear fails to niove from said position a corresponding lever willfail to swing from said vertical position, and the operator, noticing said condition, will be able to manipulate the foot pedal to urge the recalcitrant gear into a proper position. It will be understood that, in addition to the function of the levers 28 and Qt l to indicate the positions ot the gears, they may be used as ordinary manually operated gear shifting levers independently of the 'power transmiting mechanism.

It will be observed, by referring to S, that rwhen the floating lever 71H,is to be constrained by the lng 78 of a lever 77, the

free end of said lever is in a recess of the seg lector 80, and that said selector may be revolved to force said free end upon. its periphery similarly with the free ends of the other levers, With their lugs alongside the floating levers. If the foot pedal be now depressed, then du 'ing the first half of the revolution of thevshaft 44., which results in the pairs of brackets 67 and 68 approaching one another,.the bar 34B is moved from its real-most position frontwardly by the rod of the brackets 68, which movement is trans initted to the lever 28h to swing it into a vertical position in alinenient with the lever 28a to cause the arm BO" to *shift the gear Q-3 rearwardly freni the gear Gr3 into a` neutral position during the first half of.

the -revolution `of said shaft, while during the last half of the revolution there will be no displacenient of the gears, in view of the fact that the floating levers are 'tree to'inove relatively to the bars Bela and 34.-" when the hooks are held by the springs above the lug 70 whereby they are prevented from engaging the bars 34a and 34; with their hooks T2 to cause the shiftfable gears to move awayl from their neutral positions. On' the other hand, should the selector be turned until .the free end oit a non-limiting lever whose lug was iii alineii'ient with the lloating lever 'Yll is within a( recess of said selec tor, saidlugavill be forced on top of said Heating lever, and during the last half of the revolution of the shaft Lll said loating lever will be forced with its hook into the recess between the lugs of' the bar` 34h and become engaged with the inner side of the frontward lng of said bar and force said bar into its foremost "position, which Inovement will cause the' lever 28h to swing past its vertical position from its position of Figl and cause the arni 30b to shift the gear 2-3 through its neutral position and speed,

.its driving element, and the rod 35, which is shown to be operatively connected with tlie foot pedal, forces the block 57 rearwardly, whereby the hooks 58 and 62 are .forced out oli the notclie h their iioolrsthus supported, 'the wedge of the lever 6l forced ont yof the notch of the block 53 and the shaft 44: is released by the butt end 85 being 're-- moved frein the lu@r 86. but although the spring S7 orces the bolt 53 in Athe direction of the collar 5l, the yoke 5@ of tlie lever 58 :forces said collar with serrated tace away from` the shaft el and into a position wherein the bolt remains outside of its ser rated tace, wherefore vthe transmitting mechanism becomes disconnected from the driving element.

To change to'tlie first or low speed, the

selector may be turned 'until the free end of a nonelloating lever whose lug is in alinenient with the floating lever ll enters a recess of the selector, and by depressing the 'foot pedal, which. has the etleet to release the collar 5l to he forced by its spring 52 into a A position wherein the shaft el becomes connected with the driving element, the rocl 69 of the pair of brackets 67 forces the bar 34h rearwardly, which causes the lever 28h to swing frontvrardly into a vertical position and the gear Qm is forced ont of mesh with the gear G2 moved into its neutral.

To reverse the speed, the selector is turned until the free end of the nonvlloating lever Whose lug is alongside the floating lever 7lR enters a recess of the selector, and by depressing the foot pedal, the rod 69 of the pair of brackets 68 forces the bar 34e frontivarclly, whereby the lever 28a is caused to swing from. its frontward inclination into a vertical position and the arin 30 forces the gear R out of mesh with the gear -GR and into its neutral position, whereupon the said bar 3l is forced by the hoolr of the floating lever 71R frontwardly, cans ing the lever 289' to swing from its vertical position rearwardly xand the arin 30"v forces the gear R from its neutral position.
